2. Papaya over oranges
Papaya has about 15 times the amount of beta-cryptoxanthin than oranges. Studies have discovered that this phytonutrient, which is a powerful antioxidant that can prevent free radicals from damaging your cells and DNA, can reduce the risk of developing lung cancer by more than 30 percent and the odds of developing rheumatoid arthritis by 41 percent. Beta-cryptoxanthin is also found in yellow apples, lemons, grapefruit, and mangoes.
